Savage 5t Convert, what power package is best ??

I agree with lincpimp, the mmm on 6s will handle esc brakes without a problem. I have 5 mmm's running 6s with esc brakes and have built 3 other trucks running the same setups. I think the whole "headroom" for brake spike is just a bunch of people scared to run 6s. If CC says it will handle 6s I believe them 100%. I had a Savage/mmm/1515 2.5d on 6s that had unreal power, so I think your stretched truck will have no problems. Your tire size is still in line with 1/8 scale monster trucks so no problem there. Forget the mech brakes, run esc brakes, truck will look a lot cleaner.

As far as diffs go, I ran the Cen Gen gear conversion without problem. I have no experience with the new "super diffs" from HPI. Seems like HPI would have just included the Super Diffs stock in the FLux. They were really advertising that the FLux could run on 6s, and then installed stock nitro diff gears. Not impressed.

I would like to see some one or company come out with a real 1/4-1/5 scale brushless monster truck. I have seen some conversion, planned on building something myself, but there really isn't and hubs/axle shafts/diffs that can handle a real 1/4 scale monster truck size tire coming off a 20 ft jump. I'm talking about running a Red Cat Racing size monster truck size tire. They are very big and twice as heavy. Even a HPI Baja would have a hard time handling the Red Cat size tire, during bashing sessions.

I'm talking about a truck that would use a Neu 2215/2230 size motor 10-12s lipo setup and move around 50mph. It could be done, with some modeling of parts, cnc machining and time. Of course we still need a CAR esc that can do 10-12s.
